Narrative:

While en route, approximately 1 hour from arrival, dfw, the crew noticed an abnormal fuel burn. Main tank fuel had approximately 1000 pounds in each tank with center fuel tank, capacity at about 9000 pounds. Crew consulted the MD80 QRH and complied with all appropriate checklists. Captain radioed dispatch and the crew was advised that there would be no appreciable effects with this fuel load pertaining to center of gravity or structural concerns. Flight proceeded to dfw and landed without further incident. During completion of the QRH checklists, it was discovered that circuit breaker J-21 (aft center fuel pump) was tripped. This was problematic for another crew on the flight previous to this flight, written up in sea, flight on oct/mon/03. Maintenance replaced the referenced circuit breaker. All fuel pumps were verified operational prior to departure, during the originating checklist performed by the first officer. First officer reporting.
